Conventional produce: Which has the most pesticides?

As a general rule, skinless or soft-skinned fruits and vegetables pose greater pesticide risk than produce with thick skins, shells, or peels that are not eaten. According to The Organic Center, imported berries, grapes, leafy greens, and other highly perishable foods have pesticide-residue scores as much as two or three times as high as the same domestically grown foods, so it’s worth noting where produce items come from.
